My invention relates to and more-- particularly to; a pump that isoperated by cam rocking means and wherein certain'ob-'jectsoftheinvention are to provide a pump that is made relatively highin efiiciency by utilizing the laws of gravity-and the forcesgeneratedhthereby together with the aid of small additional forces;

TWithuthe above and other objects in view which will appear as thedescriptionproceeds, the invention consists of the novel Construction,adaptation, combination and. arrangement of parts hereinafter describedand claimed, These objects are-accomplished by devices illustrated inthe accompanying drawings; wherein v Figure 1 is a view in sideelevation of'the Pu p;

Fig.2 is a top plan View of thesame;

Fig, 3 is a view in transverse vertical sectiontaken substantially ona-broken-line 3, 3. of-Fig. 1; i

Fig. 4 is an enlarged fragmentary View in vertical section takensubstantially on a brokenline 4, 4 of Fig. 3; and

Fig. 5 is a somewhat diagrammatic view in; vertical section showing thecourse-of the: water through the device. I v f Referring tothe drawingsthroughout which like, reference numeralsdjesignate like;

parts, the numeral 5 indicates; the; frame of the pump which isniountedon a-base 6 com-V prisinga plurality of f-beains secured together. Atrack 7 1 comprising two rails is mounted on said base and isarrangedfor lateral displacement as more fullyQhereinaftcr set forth.-Saidv track is adapted tobe aligned with short fixed end supportsS thatare eight, in number as; clearly shown in Fig, 2off'the drawings. V

The rocking means for the device comprises a. heavy weight Qthat isprovided with two sets of canis' 10-andl1 respectively. These camsareadapted to ride on the track 7 and 5 are so proportioned with respectto the; frame 5 that the rocking means :as a whole will make a halfrevolution and completely'reverse its position as shown in dotted linesin- F ig; 1 upon rolling fromone'end of the frameto the other. e

tion as will'be understood.

Thecams 1.0 are provided with'two inches greater, eccentricity attheirlower endssolthat when the rocking device rollsifrom, its, fullline position to itsdottedi position it willtrave down-hill so tospea-k. Likewise the cams ll have a corresponding, eccentricity at"their upper ends and will roll down hil lin) passing from-the dotted'tothe full line post;-

The high points of the iirstqiamed eccentricsare disposed one hnndrediand eighty degrees fromfl the high-points of the-other pair; ofeccentricsi 'lhe, cams; 10 travel on the track' -7 while: injitsfoutwardorfull line position as shown-insFigflwhem the rocking device. moves totlie dottedposis tion inFigfl, and the cams 11 travel onsaid I track initsfnarrowed or dotted position when rolling back to the full lineposition. Itwill be understood that in boththe fullanddotted" positionsof said cams,- as showrrin Fig.2, they arelcompletely supported by thefixedeend. supports 8 and are entirely free of the, track. 7, leavingsaidtrack freeto' be: shifted laterals ly back and forth into;alternative alignment. Wit-h said stationary end supportsf The means forautomatically shifting;the track 7 comprises a shaft or rod l2ithat=exetends. centrally between said. tracks and is journaled ,to. the frame .5at bothsof. its-ends; A finger 1 3 isifixed to each endvportion of saidshaft vertically 'above'thefixedtracleend. supports 8; Yokes 1 arekeyedyte the-sliaf-t, and connected to thejrails of-the trackmby'linksl5. Thus? at the endof: its stroke andv wheniresting on said'trackend supports-the Weight-9 engages one of the fing'ers causing the shaftto 1 revolve whereby the links draw the traclginwardly to'the dottedposition, and: at the, end of its other stroke said Weight .en-- gagesthe; other and oppositely disposed finger. whereby the track willbeex'panded to its original position; The track i'srthus caused toalternatively register. with-thefixedendsupportsvin keepingwith theeccentric disposition of the cams-1O and 11 as the rocking device rollsback and forth.

For; the purpose of retaining the weight 9 at rest in an uprightposition for aishort length of time at .either-cndof its strokie arms' 116 are securedltheretdand areprovided-Iwith;

rollers 17 Stop members 13 are secured to the upper portion of the frame5 at either end. Said rollers glide over the tops of said stop membersand roll down against their rear sides while the weight 9 is settling toits lowered position shown in Fig. 4. Thus the rollers and stop membersrestrain the rocking device as a whole from beginning another strokeuntil said weight has reached its clownward limits and the rollers arethen free to pass under said step members as the weight begins itsreverse movement.

Asa means for stopping the rocker device I have provided a pairaofhooked levers 19 that are pivoted to opposite sides of the frame 5 at20., The hooked ends of said levers by means of their weight arearranged to alternatively engage rollers 21 mounted on the end portionsof the rocker frame. A hooked arm 22 is pivoted to each of said leversand their hooked ends are arranged to alternatively catch on lugs 23fixed to the rear of said weight. A rod 24 slidably mounted on the frameis provided with cams or fingers 25 which engage the arms 22 and holdthem in the paths so that their hooked ends will engage said lugs. Bypulling said rod the hooked ends of said arms are disengaged from saidlugs and the rocking device will be stopped at either end of its stroke.

The Weight 9 is provided with a water chamber 26 at both its upper'and'lower ends and said chambers are enclosed by cylinder heads 27 thatare secured to the frame of the eccentrics l0 and 11. Said weight fitssnugly in said cylinder heads and is free to slide up and down forreasons presently apparent. An anti-friction roller 28, mounted on theframe of the cams 10 and 11, engages the weight and helps to support itduring the movement of the rocking device as will be understood.

" Intake tanks 29 at either end of the machine are connected by a pipe30 and an intake pipe 31 extends therefrom to the source of watersupply. A discharge tank 32 is superimposed on each of said intake tanksand said discharge tanks are connected by a pipe 33 and a discharge pipe34 extends therefrom to the point of delivery for the water. A manifoldpipe 35 connects each intake tank with its associated discharge tank anda flexible hose 36 and 37 extends respectively from each of saidmanifolds to the upper water chamber 26 on its respective side. In otherwords the flexible hose 36 extends from the manifold 35 on the right tothe water chamber 26 which is, for the time being, the upper waterchamber when the weight 9 and its cams is at its right hand position asshown in full lines in Figs. 1 and 4, and the flexible hose 37 extendsfrom the manifold 35 at'the remote or left hand end of the device to thewater chamber 26 which is the lower chamber in this particular position.Fingers 38 are to the other side of the frame 5. Said weight in movingdown has forced the water from the lower chamber 26 through the hose 37into the discharge tank 32 on the other end of the frame. At the sametime said weight in moving down hascreated a vacuum in the q upperchamber26 whereby said chamber has been filled with water by suctionfrom the intake tank 29 on the right hand side.

In Fig. 5 an arrangement of flap valves is shown whereby the water isdiverted from the intake tanks 29 to the discharge tanks '32. Asdescribed immediately above, the

water has been drawn from the intake tank 29 on the right into the upperpump chamber 26 and an intake flap valve 39 in the manifold 35 is openedupwardly while a discharge flap valve 40 in said manifold is closeddownwardly. At the same time the water has been forced from the lowerpump chamber 26 into the discharge tank 32 on the left whereby adischarge flap valve 41 is opened upwardly and an intake flap valve 42is closed downwardly. It will thus be observed that this arrangement isreciprocal in that the discharge and intake valves are alternativelyopened and closedand that the positions of said valves will be reversedon the other stroke of the rocker device. The intake tanks 29 areactuated only by suction while the discharge tanks 32 are actuated bypressure and the pressure forces the water alternatively from saiddischarge tanks through the pipe 33 and the discharge pipe 34. i

To completely carry the rocker device to the ends of its strokes a watermotor 43 is used. Said watermotor is provided with a shaft 44 supportedin'suitable bearings on the frame 5 and having a pulley 45 on each ofits ends. Cables 46 extend from said pulleys to sheaves 47 mounted onthe other end of the frame. Said cables are pivotally fastened to therocker frame at 48 concentrically with the cams 10 and 11. To operatesaid water-motor a small blow pump 49 driven by an electric motor 50 isused as shown in Fig. 5 of the drawings. The water for said blowpump istaken from the discharge tank pipe connection 33through a pipe 51 andafter being forced through the water-motor 43 the water is returned tothe intake tanks through a pipe 52 joined with the intake connectingpipe 30. i

It will be understood that the cables 46 have no great pulling power andare primarily intended for the purpose of giving the rocker device itsinitial start or movement from its state of rest at the ends of itsstrokes. It will also be understood that the electric motor is only ofsufficient power to operate the water-motor 43 to the extent ofinitially moving said cables. The water for operating said water-motoris already under considerable pressure, being taken from the highpresrodis provided at either end'portion with a fin er 57 and saidfingers are engaged by the roclzer device at each end of its strokewhich causes the crank rod to give the valve core 543a quarter turn.Said valve core is provided with two longitudinal cross openings '58which are shown in registry with the pipe connections in Fig. 5 wherebythe water-motor 4L3 will rotate as indicated by the direction arrows.Said valve core is'al'so provided with two transverse openings 59disposed substantially at right angles with said crossed openings andwhen said valve core is given a quarter turn by the means ust describedsaid transverse openings will be brought in line with the pipeconnections thus changing the direction of flow and reversing thewater-motor 4:3 as will be understood.
